Preparing for the Test

Test preparation requires that you/your child have no food, calorie containing drinks, or caffeine 4 hours before the test. Water and caffeine-free, calorie-free drinks are allowed. Avoid exercise for 4 hours prior to the test.

During the test

During this test, you breathe into a mouthpiece on a handheld device while sitting at rest. The device is portable so it will take place in the dietitian’s office. If you are an inpatient the test will take place in your room.

Length of the Test

The appointment will take about 30 minutes.

On the day of your scheduled test, report to the clinical nutrition check-in. It is located in the basement of the May building. If you are an inpatient, the test will take place in your room. If you have questions, please call 303.398.1889.
